Question:
Find a vector and a unit vector perpendicular to the vectors 3i-4j+5k and -2i+j-3k
solution:
The vector product of 'a' and 'b' is represented by :
HLO MATE HERE IS UR ANSWER.
GIVEN VECTORS ARE.
a = 3i - 4j + 5k
b = -2i + j -3k
❤. SCALAR PRODUCT ❤
a.b = [ 3i - 4j + 5 k ] . [ -2i + j -3k ]
= -6 -4 -15
= 6+4 =10
= 10 + _15
= -25//.
❤. VECTOR PRODUCT ❤
a × b = | i j k l
l 3 -4 5 l
l -2 1 -3 l
= i [ 12 -5] - j [ -9 -(-10)] + [-3-(8)]
=7i-j [-9+10] + k [-5]
= 7i -j-5k.
